"Justified" (FX, January 8)

It's always a pleasure to go back to Harlan to watch Tim Olyphant and Walton Goggins spar, this year with an eclectic group of guest stars including Ron Eldard, Patton Oswalt and Joseph Mazzello. The fourth season will go back in time in a way, as Raylan looks into a 30-year-old case with ties to his father's criminal past, while Boyd gets into a rivalry with a Pentecostal preacher who's nearly as charismatic as Boyd himself. This, we need to see.
